I'm not sure if I posted elsewhere on this topic. Maybe I did, but here's what I've learned lately..
After installing some outdoor LED lighting on my garage, I had a real bad bug problem!
The bugs were leaving a large amount of droppings on the fixture and on the green sidling.
The mess was so bad, it took a lot of work to clean up. Soap, brush, water hose & etc..
I Put them on timers and them, but soon went to an IR motion sensor..
They go on for about 5 minutes when motion is detected in the driveway..
Mostly, they never come on during most nights..
For me, this is the only way to use outdoor lighting in this area.. Too much bug poop..
